What specific vow did Cholkar make to Sai Baba, and what were the circumstances that led him to make it?

Cholkar, facing financial instability, made a vow to Sai Baba out of desperation. As described in Chapter 15, he came from a poor household where everything depended on his job. To make his salary permanent, he needed to pass an examination. The stakes were high, as failing meant his daily bread was at risk. In this situation, he made a firm resolve, vowing that if he passed the examination by Baba's grace, he would present himself at Baba's feet in Shirdi and distribute sugar candy (khadisakhar) in Baba's name. This vow was a direct appeal for divine help to secure his livelihood.
